6. write the converse of the following true conditional statement. if the converse is false, write a
counterexample
(1 point)
if a < 10, then a < 15.
if a > 10, then a > 15: false
counterexample: a = 12 and a < 15
if a < 15, then a < 10: false
counterexample: a = 12 and a > 10
if a < 15. then a < 10: true
if a 2 15, then a 2 10: true

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
